Abstract
The characterization of the superficial topography of a thin film, obtained from an interferometer installed in our Optics Laboratory, is done using bi-dimensional images of its surface overlaid with interference fringes (interferogram1). These images differ among them only by a constant variation of the optical phase2. The total number of images to acquire depends on the image processing algorithm to apply; this algorithm allows to determine the value of the phase introduced by the surface form.
